The aim of this lecture is to present on Sales Aptitude Criteria for Selecting Salespeople. A number of variables are related to salespeople’s psychological traits and abilities. The exhibit defines seven subcategories of personality traits, five groups of other enduring aptitude factors or mental abilities and five groups of skills. Separation costs, such as those associated with exit interviews, separation pay, increases in unemployment taxes, and administrative expenses. The strengths of the relationships between some categories and sales performance vary according to the type of customer and the kind of product or service being sold.
